Diffusion Modeling

## Warning: package 'bindrcpp' was built under R version 3.5.3

Diffusion Model Parameters

• a = boundary separation
• z = starting point (parameterized here as a proportion of boundary separation)
• t0 = lower bound of non-decision RT component
• st0 = range of uniform distribution of non-decision times. NDT distribution is U(t0, t0+st0)
• v.L = drift rate for lures
• v.W = drift rate for weak targets
• v.S = drift rate for strong targets
• sv.L = inter-trial drift variance for lures
• cv.T = inter-trial drift variance for targets (both weak and strong)

UVSD Model Paramters

• d.W = Mean of “weak” target distribution
• d.S = Mean of “strong” target distribution
• s = Varaibility of both target distributions
• crit1 = Threshold for conservative bias condition
• crit2 = Threshold for neutral bias condition
• crit3 = Threshold for weak bias condition
